BACKGROUND OF THE INVENTION

1. Fields of the Invention

The present invention relates to a curtain frame, especially to a curtain frame that is fixed on a ceiling or installed between walls on two sides so as to meet practical needs.

2. Descriptions of Related Art

In interior decoration, curtains are used for privacy, light control, decorative aspect of the wall, and noise absorption and isolation. According to different functions, there are various kinds of curtains. For example, different areas inside the house have different requirements of curtains for privacy issues. In the living room, a slightly more transparent curtain is selected while a thick and heavy fabric is used in the bedroom. Moreover, a light curtain fabric such as scrim curtain is used to offer light effectively and still giving privacy. Furthermore, the curtain with certain thickness not only absorbs outside noises but also improves the effects of sound insulation inside the house. Thus better indoor sound quality is provided. In addition, the proper curtain makes the perfect decoration for your room.

Refer to U.S. Pat. No. 6,935,401, a window treatment or roller shade system 6 includes a head rail 61, a spring clutch 62, disposed on one end of the head rail 61, an idler arranged at the other end of the head rail 61, and a pair of brackets 63 mounted along the ends of the head rail 61. Each bracket 63 includes a first engagement member arranged and constructed to couple to the spring clutch 62 and a second engagement member arranged and constructed to couple to the idler.

The two brackets 63 are identical while one bracket 63 is selectively coupled to the spring clutch 62 by its first engagement member and the other bracket 63 is coupled to the idler by its second engagement member.

However, in practice, the above window treatment or roller shade system has following disadvantages:

1. In the window treatment or roller shade system, the head rail is only a thin plate so that the head rail is assembled on a side wall by brackets on two ends thereof. The industrial applications of the device are reduced. 2. The head rail of the window treatment or roller shade system can only protect a front side of the system but not cover on the top thereof. Thus dust easily gets into an inner space of the system. This not only causes inconvenience in cleaning but also has negative effects on operations of the system components such as the spring clutch.

SUMMARY OF THE INVENTION

Therefore it is a primary object of the present invention to provide a curtain frame that is fixed on a ceiling by disposition of fix bases on a top horizontal rail thereof. Or the curtain frame is installed between walls on two sides by the brackets arranged on two ends of the top horizontal rail thereof so as to meet practical needs. Moreover, the top horizontal rail prevents dust and dirt from approaching the inner space of the curtain frame and further keeps the cleanness therein. The normal operation of the components in the curtain frame such as a curtain controller is also ensured.

In order to achieve above object, a curtain frame of the present invention features on a top horizontal rail having a top plate and a side plate, connected with each other to form a L shape. Moreover, a bracket is connected with each of two ends of the top plate and a curtain controller is mounted between the brackets. A central shaft of the curtain controller is a rotating shaft arranged rotatably for control of extension and retraction of a curtain. One end of the curtain controller is arranged with a bead chain that drives the rotating shaft to rotate. And a guiding seat is set on the flange on the bottom of the bracket assembled with the curtain controller. The guiding seat is mounted with a plurality of through holes that are inserted by the bead chain of the curtain controller. Furthermore, a plurality of fix bases, each with a plurality of holes, is locked on the top of the top horizontal rail. The fix bases are fixed on the ceiling by threaded fasteners inserting through the holes of the fix bases.

In a preferred embodiment of the present invention, the top plate and the side plate are connected integratedly.

In a preferred embodiment of the present invention, the top plate and the side plate respectively include a connection part, corresponding to and connecting with each other.

The first mounting slot 13 and the second mounting slot 14 adjacent to each other are formed on the top surface of the top plate 11 so as to connect with the bracket 2 and the fix base 5. The fix parts 15 are located on the bottom surface of the top plate 11 so as to fasten with fix members 27 of the bracket 2. The third mounting slot 16 for connecting with the bracket 2 is on the inner wall of the side plate 12.

A top surface of the bracket 2 includes a first mounting plate 21 and a second mounting plate 22, adjacent to each other, respectively corresponding to and assembling with the first mounting slot 13 and the second mounting slot 14 on the top horizontal rail 1. Moreover, a pivot part 23 or a plurality of locking holes 24 is/are arranged at a center of the bracket 2 so as to fix the curtain controller 3. A plurality of insertion holes 25 is disposed around a circumference of the bracket 2. A side piece 26 is arranged on an outer side of the bracket 2 correspondingly. A plurality of locking rods 261 corresponding to the insertion holes 25 respectively is disposed projectingly on the side piece 26 so as to lock into each insertion hole 25 firmly. Furthermore, a plurality of fix members 27 inserted through and arranged at the circumference of the bracket 2 are fastened with the fix parts 15 of the top horizontal rail 1. A third mounting plate 28 is formed on a lateral side of the bracket 2 and is connected with the third mounting slot 16 of the top horizontal rail 1 correspondingly. Also refer to FIG. 5, a flange 29 for disposition of the guiding seat 4 is set on the bottom of the bracket 2.

A central shaft of the curtain controller 3 is a rotating shaft 31 arranged rotatably for control of extension and retraction of a curtain 35. The curtain controller 3 is arranged with a bead chain 32 that drives the rotating shaft 31 to rotate. At least one locking block 33 corresponding to the locking hole 24 of the bracket 2 is disposed projectingly on a surface of one end of the curtain controller 3 so as to lock into the locking hole 24 while a pivot member 34 is arranged at the other end of the rotating shaft 31 so as to pivot with the pivot part 23 on the center of the bracket 2.

The guiding seat 4 is mounted with a plurality of through holes 41 that can be inserted by the bead chain 32 of the curtain controller 3. Moreover, the guiding seat 4 further includes a side cover 42 and a plurality of fastening holes 43.
